Submersible Motors

In conjunction with our long standing trading partner, SDE/SME Pty Ltd, we can offer a large range of ‘off the shelf’ submersible motor and pump combinations, both hydraulic and water pumps systems. Ranging from 1kW to 400kW / 110V to 6kV. We can also offer bespoke designed ‘special’ motors to meet your specific requirements. Every motor in our catalog was a ‘special’ at some stage.

Subsea Motors


Our motor customers include ROV operators, Subsea fisheries, subsea dredging companies, subsea telecoms companies, subsea tidal energy, manned submarines operators, power station operators & irrigation depts.
We can offer a consulting service to assist you with choosing the right solutions, solving existing problems or upgrading existing equipment.
We can also offer a repair, rewind and service facility in UK, Australia & Singapore for motors up to 6000V / 500kW.

Our High Temperature Submersibles in 6″ to 20″ frames are designed with integral cooling systems for use in high ambient temperature conditions up to 75° C. These are particularly suitable for trenching systems in turbid water conditions or slow moving vehicles. A temperature monitoring unit is also available to enable operators to closely monitor motor temperature in use. Again particularly useful for the larger scale trenching & pumping systems.

Motor voltage upgrades are also available to 3000VAC, 3300VAC, 4160VAC & 6000VAC. Enabling more power from the same size motor.

All of our motors are pressure compensated and suitable for full ocean depth use. Available in Aluminium T6061 or SS316 stainless steel. All motors are fully dyno tested prior to dispatch from the factory.


SDE/SDE/SME Motor Pump Combinations for ROVs, Trenchers & Ploughs.
SDE / Submersible Motor Engineering can supply our own Pump/Motor combination.
We offer a 2- pole, or 4-pole motor coupled to our own designed pump (especially designed for trenching applications).
With a full ocean depth rating, this pump and motor combination is rigorously tested in our factory to full performance before dispatch.
